OpenXava 4.2.3 released

Lesson 4 of OpenXava course

January 16, 2017

We're working hard to upgrade the current OpenXava course that is based in OpenXava 4 and in PDF format to use OpenXava 5 version and wiki format. We are pleased to announce that we have just finished the lesson 4, now it uses OpenXava 5 features. The lesson 4 is about using inheritance to simplify your code for JPA, user interface and jUnit tests.
